'This inve-anda fanta as @easements ai f loom motionsLand particu to al lmove'- me'nt regulating means for the. battemand it is the principal ob]ec`t of the invention the atten at the eiid of its motion as much as possible in order to allow the spools as much time as possible to pass through the warp, while allowing the batten to move as quickly as possible towards the harness.

Another obj ect of the invention is the provisionl of a loom movement of simple and therefore inexpensive construction, and one which may readily be installed in any of Y' the looms of the present day.

A further object of my invention is the provision of a loom movement which is durable, positively acting and efficiently operating.

These and other objects of my invention will become more fully known as the description thereof proceeds, and will then be specifically pointed out in the appended claims.

In the accompanying drawing, forming a material part of this disclosure: Fig. 1 is a front elevation of my improved batten movement.

Fig. 2 is a top plan view thereof.

As illustrated, the loom frame has journaled therein a shaft 11 for the driving pulley 12 over which a belt 13 is guided for transmitting the power of a motor or other source of power to the batten movement device.

The shaft 11 carries also a gear 14 in juxtaposition to pulley 12 which meshes with another gear 15 on a shaft 16 journaled also in the loom frame. The'gear 15 has an eccentrically arranged pin 17 projecting from its side face into and through a slot 18 in the side of a member 1-9 extending in the direction of the longitudinal axis thereof. The member 19 has formed at its rear end a stub shaft 20 which carries a bevel gear 21 meshing atl one side with a be'vel Y gear 22 on the crank shaft 23 driving the to povide a loom withmiaris fo' .delaying operation o'fA my device clearly aaaerstaoa fraai the atea@ asripaog @a the ent, that during-', the' rotation of t e gears' 14, 1,5" aitdd25fhthepin,of 1 5 will bey displaeed inthe slot 18`of member 19 in such a manner that the slowest motion of the batten operating crank shaft takes place when the pin 17'is near the inner end of the slot of member 19 or closer to the pivot point of said member than to its free outer end, in order to delay the batten movement at th-e end of its rear motion, as much as possible for allowing the spools Vas much time as possible to pass through the warp, while not interfering with the quick movement of the batten towards the harness.

It is to be understood, that while I have shown and described the preferred form of my invention as an example of the many ways in which the same is to be practically constructed, such changes as come within the rscope of the appended claims may be made in the construction of the minor details of my invention without departure from the spirit thereof. o

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent is:

1. A batten operating device for looms comprising a plurality of intermeshing gears journaled on shafts arranged in the frame of the loom, a means for transmitting the power from a `source of power to one of said gears, one of said gears having a bevel face, a slotted member having a stub shaft at one end, a bevel gear on said stub shaft meshing with said bevel face, a crank shaft, a bevel gear on said crank shaft in mesh with said last named bevel gear, and a means on one of said gears adapted to engage the slot of said member to delay the hatten motion at the inner end of its path for allowing the spools more time for passingl through the warp. v

2. A batten movement for looms, particularly narrow band looms, comprising a train of gears, shafts for said gears journaled in the loom frame, a slotted member pivoted at itsrear end and extending longitudinally to the front faces of the gears of said train of gears, a pin eccentrically projecting from the side face of one of said gears into said slot of the said member, a head on said pin, a'plurality of bevel gears adapted to be actuated by said train of gears, and a crank shaft for operating the betten Carrying one of said bevel gears adapted to be delayed by the elidiilg` pin :it the rearmost end of its path within the slot oil? seid member `for allowing; more time for the spools to pass through the werp.

3. ln e leoni, :1 devlee for delaying the hutten motion at the end of its rearward path for allowing the spools to pass slowlyY through the dirp, smid device comprising a trein olr gears ol equal size in mesh with one another, a means for driving one of said gears. u bevel gear formed :1t the inner face ol the lust gear, e member slotted at its side edge and pivoted at its rear end, a steh shaft 'foi-ined et this rear end, a bevel gear on said stub shailt n mesh with said bevel face, a erzink shaft operating the betten, a.v bevel geur on said shaft in lnesll with seid stub shaft gear, en eecentriczllly projecting pin on the side fece of one of seid gears projecting in the slot of said lneinber, :L head on said pin, seid pin adapted to delay the betten movement et the end oi its inner path for Allowing' to the spools more time to pass through the werp.
